Proximity communication

Conserving Memory Bandwidth in Chip Multiprocessors with Runahead Execution

“…We deem these approaches orthogonal to fine-grained fetch since compression of sub-blocks could further alleviate the bandwidth problem. Proximity communication [11] appears to be a very promising new technology. If proven successful it could very well disrupt current bandwidth trends.…”

Designing multi-socket systems using silicon photonics

“…Proximity interconnect [4] is an interesting technology that is trying to solve many of the same problems our photonic socket-level interconnect is. It places dies very close together and uses capacitive coupling to transmit data without actual wire contacts.…”

A 14-Gb/s 32 mW AC coupled receiver in 90-nm CMOS

“…The hysteresis circuit in [2] used a single ended CMOS latch and was limited to 1 Gb/s in a 0.35 um process. This single ended architecture suffers from common mode disturbances such as ground and power supply noise.…”

“…Data rates above 1Gb/s over 50-150 fF capacitively-coupled interconnects are demonstrated in [1], [2] as a possible solution for System-In-Package (SiP) applications. In this design we propose a novel receiver architecture ( Fig.…”
